13. Measure the clutch pack height.

    	Description	Reading
    A.	Place the clutch pack with the pressure plate on to the special tool with the wave spring down. Slide the clutch off to the side so the probe of the dial indicator is touching the gauge plate of the special. Zero out the dial indicator.
    B.	Carefully lift the probe up enough to slide the clutch pack under the probe to take a reading. Record this reading. Rotate the clutch pack 180 degrees and take a second reading. Add the first and second readings together and divide the total by 2. Record this reading as B.

14. Measure the piston to center support shoulder height.

    Description	Reading
    Measure the piston to center support shoulder height. Record this measurement. Rotate the center support 180 degrees and record this measurement. Add the first and the second measurements, then divide by 2. Record this as reading C.

15. Calculate the end clearance.

    Description	Reading
    Total C measurement
    Subtract B and C from A to determine end clearance
    Minimum end clearance specification	5.08 mm (0.200 in)
    Maximum end clearance specification	5.73 mm (0.226 in)

    Compare the end clearance to the specification. If the end clearance is out of specification, select the next thinner or thicker plate as required and repeat Steps 10, 11 and 12.
